RESULTS
A total of 41 studies were identified after duplicates were removed, and
32 studies were excluded based on the title and the abstract (11 were
not performed for acute asthma, 13 did not use systemic corticosteroids
in both groups, 5 did not specify the data for children, and 2 RCTs did
not include intervention drugs). We performed a full text review of nine
articles, 20-28 all of which met our inclusion
criteria and were counted in the quantitative and qualitative analyses
(Figure 1).
